Human growth hormone (HGH), also known as somatotropin, is a peptide hormone produced by the pituitary gland. HGH plays a vital role in stimulating growth, cell reproduction and regeneration. However, HGH is not a steroid. There are several key differences between HGH and steroids:
- Steroids are synthesized in the body from cholesterol or steroid precursors. Common examples are testosterone and estrogen. On the other hand, HGH is directly secreted by the pituitary gland, a pea-sized gland at the base of the brain.
- Steroids have a characteristic structure based on four carbon rings. HGH has a completely different chemical structure made up of amino acids.
- Steroids binds to steroid receptors in cells to trigger biological effects. HGH binds to growth hormone receptors, activating different signaling pathways.
- Steroids primarily impact anabolic processes like building muscle mass. HGH stimulates wider range of effects on growth, metabolism etc.
- Unlike supplements containing steroids, supplements that claim to boost HGH levels are not effective and should be avoided.
So in summary, HGH and steroids are chemically unrelated hormones that influence different biological pathways. While steroids are abused to enhance athletic performance, HGH is not a viable shortcut.
Some key points about HGH:
Effects of HGH
- Stimulates tissue growth by increasing protein synthesis
- Increases calcium retention and strengthens bones
- Boosts muscle mass and reduces fat
- Supports metabolic processes producing energy
Medical uses of HGH
- Treat growth disorders in children
- Muscle wasting due to HIV/AIDS
- Short bowel syndrome
Potential side effects
Prolonged HGH treatment can lead to side effects like:
- Joint pain
- Muscle weakness
- Fluid retention
- High cholesterol
- Diabetes
Safe levels
- Natural HGH production decreases after early adulthood
- Replacement therapy involves daily injections in very small doses
I aimed to provide an overview comparing HGH and steroids, explain the mechanisms of HGH and highlight that supplementation is not recommended for enhancing performance or aging. Let me know if you need any clarification or have additional questions!
